House Extension Drawings in Hither Green |

No Article 4 Direction covers Lewisham, which keeps the Hither Green permitted-development route open on unlisted houses. The fabric of Hither Green is Edwardian terraces, 1930s semi-detached, so a SE13 proposal is judged on fit before it is judged on size. Lewisham has 30 conservation areas, and Deptford High Street is the one that most often covers Hither Green stock. We plot the Hither Green site against the designation before quoting.

We check Article 4 directions against the Hither Green address first — it changes what is worth drawing. A Hither Green survey establishes the edwardian terraces dimensions that decide the scheme — original rear wall, floor levels, and ridge height against Mountsfield Park. The borough policy layer over every SE13 address is set out on Lewisham planning. The Hither Green survey then carries into architectural drawings in Hither Green if the project runs on to construction.

The Hither Green clock does not start until London Borough of Lewisham validates — one to two weeks. The first visit to Hither Green is a measured survey — every room, every opening, every level change recorded on site.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

After validation a Hither Green application is allocated to an officer, who will visit the SE13 address. Output for Hither Green: dimensioned PDFs at the scales the authority specifies.

Speaking to SE13 neighbours before submission avoids most of it. Roof pitch and eaves height on a Hither Green house are measured, not scaled off.

Party wall procedure runs alongside the Hither Green application, not after it. Once consent is granted, planning permission follows for the SE13 property.

Hither Green is characterised by edwardian terraces, 1930s semi-detached, concentrated across SE13 in the Lewisham / Hither Green area. On Hither Green streets the edwardian terraces sets the structural grammar for everything that follows. Applied to SE13 property: edwardian plots here are wider, so a wraparound picking up both the side return and the rear is normally achievable within the 4 m detached / 3 m attached limits. It is why the Hither Green existing set is measured, not traced. Ridge and eaves lines along Hither Green streets are the reference Lewisham Council uses.

Lewisham Council assesses Hither Green basements on standard grounds. Because the Hither Green survey is drawn properly once, building regulations drawings for SE13 properties and loft conversion drawings build on it rather than starting again.
